SHUTTLE-CHECKING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent N 0. 738,255, dated September 8, 1903. Application filed June 13,1903. Serial No. 161,25 i. (No model.)

To all whom it nuty concern.-

Be it known that I, JOSEPH E. TICHON, a citizen of the United States, residing at New Bedford, county of Bristol, State of Massachusetts, have invented an Improvement in Shuttle-Checking Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to means for check ing the shuttle in a loom and stopping the same when home in the shuttle-box; and it has for its object the production of novel means for bringing increased pressure to bear upon the shuttle as the latter approaches the end of its travel, the degree of such pressure being proportional to the speed of the incoming shuttle.

The various novel features of my invention will be described hereinafter, and particularly pointed out in the following claims.

Figure l is a top or plan view of one end of the lay of a loom with a shuttle-box thereon having one embodiment of my invention applied thereto, the box being empty. Fig. 2 is a similar view, but showing the shuttle boxed and the checking mechanism in operative position. Fig. 3 is a rear elevation of the outer end of the lay and binder, showing the eccentric-fulcrum for the outer end of the latter. Fig. 4 is a side elevation, detached, of the device on which the binder is fulcrumed; and Fig. 5 is a top or plan view thereof.

Referring to Fig. 1, the lay A, the front wall I) of the shuttle-box fixedly mounted thereon, the top or cover plate I), back wall 19 the longitudinal slot a in the lay, and the picker-stick P, movable therein and having the attached picker P may be and are of well-' known or usual construction. The lay is shown as having mounted thereon the usual protector rock-shaft 1), having an upturned binder-lingerp and a controlling-spring S Fig. 1, all as usual, the finger cooperating with the inner end b of the binder B. A long pin or stud cl is extended loosely through an upright hole in the lay near its outer end behind the slot a said stud having fast upon it an eccentric elongated head CV and a lateral arm cl, broadened at d Fig. 5, at the base of the l1ead,aud resting upon the lay, the stud being extended above the head at d to pass through the outer end of the coverplate band receive a retaining-nut 5 upon it. The binder B, which is shown of substantially common form, has a circular opening made in its outer end to receive with an easy fit the head d ,.the latter forming the fulcrum upon which the binder is pivotally mounted. As shown best in Fig. 3, the binder rests upon the enlarged portion (1 of the arm (1, the latter normally extending acrossthe slot a in the path of the pickerstick.

Referring to Fig. 3, a collar 6 is shown secured to the stud d beneath the lay to prevent lifting of the stud, and a spring e is coiled around the depending end of the stud and secured to a second collar 7 thereon, the other end of the spring being attached to the lay. The spring is so wound as to normally turn the stud in the direction of arrow 8, Fig. 1, until a stop d on the part cl engages the 1ay,.the arm d then being in the path of the picker. At such time the eccentric-head (1* is so positioned that the outerend of thebinder is held outward, as in Fig. 1, its inner end b resting against the back wall of the shuttlebox. When the incoming shuttle S strikes the binder its inner end is thrown out against the action of the protector-spring S, the binder turniugonits fulcrum (1 and the point of the shuttle then hits the picker and throws the picker-stick outward against the arm d. As the force of the blow delivered by the shuttle is greater orless the arm will be swung opposite to the arrow 8, Fig. 1, to a corresponding distance, and the eccentric-head d will be turned simultaneously. By its eccentricity to the stud d the head will act upon the binder and force its outer end inward against the side of the shuttle, checking the latter at the proper position in the box. The force thus imparted to the binder is applied when it is needed most, and it varies in power in conformity with the force of the blow delivered by the incoming shuttle, so that the latter is effective in determining the force of the checking action. When the shuttle is thrown out of the box, the spring 5? returns the stud and head (Z to normal position, moving the outer end of the binder rearward in readiness for the next entry of the shuttle.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a loom, a lay having a fixed shuttlebox wall,an opposed laterally-movable binder,

' a stud rotatably mounted on the lay and having an eccentric portion on which the outer end of the binder is fulcrumed, and means governed by the impact of the incoming shuttle to turn said stud and through its eccentric connection with the binder force the latter against the side of the shuttle.

2. In a loom, a lay having a fixedshuttlebox wall,an opposed laterally-movable binder, a stud rotatabiy mounted on the lay and having an eccentric portion on which the outer end of the binder is fulcrumed, a spring to turn the stud in one direction, and means governed by the impact of the incoming shuttle to turn itin the opposite direction and through its eccentric connection with the binder force the latter against the side of the shuttle.

3. In a loom, a lay having a fixed shuttleboxwall,an opposed laterally-movable binder, an eccentric mounted on the lay and forming a fulcrum for the outer end ofthe binder, and means to turn the eccentric automatically and force the binder against the incoming shuttle as the latter completes its throw.

4:. In a loom, a lay having a fixed shuttlebox wall,an opposed laterally-movable binder, an eccentric mounted on the lay and constituting a fulcrum for the outer end of the binder, a spring-controlled finger to act upon the inner end thereof, and means governed eccentric and force the outer end of the binder against the side of the shuttle.

5. In a loom, a lay havinga fixed shuttlebox wall,an opposed laterally-movable binder,

a picker-stick, and an arm pivoted onthe lay and having an eccentric-head which serves as a fulcrum forthe outer end of thebinder, the arm extending across the path of the picker, engagementofthe latter with the arm, due to the blow of the incoming shuttle, turning the eccentric-headand-forcing the binder against the side of the shuttle.

6. In a loom, a lay having a fixed shuttlehox wall,an opposed laterally-movable binder, a picker-stick, an arm having an elongated stud extended through the lay, and an eccentrio-head on which the outer end of the binder is fulcrume'd, said arm extendingacross the path of the picker, and a spring fast at one end and at its other end secured to the stud byimpact of the incoming'shuttle to turn the to turn the latter in one direction, impact of the incoming shuttle upon the picker causj ing the latter to engage the arm and turn the eccentric-head to force the binder against the .side of the shuttle.
